About This Workflow
How it works
This workflow automates image generation using the OpenAI API. It starts with a Form Trigger node that collects a user's text prompt and desired image size. This information is then passed to the OpenAI Image Generation node, which makes an HTTP POST request to the OpenAI API endpoint for image generations. The 'gpt-image-1' model is specified, along with the user-provided prompt and size. The raw image data is then converted to a binary format by the Convert to File node. Finally, the Return to form node presents the generated image back to the user for download, completing the automation loop.
Key Features
- Generate images from text prompts using OpenAI's advanced models.
- Select custom image dimensions (1024x1024, 1024x1536, 1536x1024).
- Seamlessly integrates with OpenAI API via HTTP Request.
- User-friendly form interface for input.
- Direct image download for immediate use.
How To Use
- Configure Form Trigger: Set up the
Prompt and optionsnode with 'OpenAI Image Generator' as the form title. Define the 'Prompt' field as required text input and 'Image size' as a dropdown with the specified options. - Set up OpenAI API Request: In the
OpenAI Image Generationnode, ensure the URL ishttps://api.openai.com/v1/images/generations. SelectPOSTas the method. Choose 'OpenAi account' for thenodeCredentialTypeand ensure your OpenAI API key is correctly set up in your n8n credentials. - Map Prompt and Size: In the
bodyParametersof theOpenAI Image Generationnode, map thepromptvalue to={{ $json.Prompt }}and thesizevalue to={{ $json['Image size'] }}. - Convert to Binary: The
Convert to Filenode should be configured to convert thedata[0].b64_jsonoutput from the OpenAI node into binary format. - Return Image: The
Return to formnode is set tocompletionoperation withreturnBinaryresponse. Configure thecompletionTitleandcompletionMessageas desired.
